Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an oil combustor having a vertically movable wick.

2. Description of the Related Art Generally, in an oil combustor having a vertically movable wick, the amount of combustion is changed by vertically moving the wick by a wick up / down lever and adjusting the rising condition of the wick.

Problems to be Solved by the Invention However, in the above-described conventional configuration, the degree of combustion adjustment has to be determined by the position of the core up / down lever, which is not convenient. It is generally considered to provide an indicator as a method of solving this problem, but in the case of the core up / down lever method, the moving amount of the core up / down lever directly becomes the moving amount of the wick, so normally the wick is only 5 to 7 mm. Even if the indicator is attached to something that cannot be moved, the display width is expected to be extremely small and difficult to see.

The present invention has been made in view of the above point, and it is an object of the present invention to make the display easy to see and to have a high display accuracy even in the core up-down lever system.

Means for Solving the Problems In order to achieve the above object, the present invention has a core up / down lever that penetrates through a front plate of a combustor body and projects forward from the inside of the combustor body, and the core up / down lever. An operation arm integrally attached to the operation arm, a display lever which is disposed along the inner surface of the front plate of the combustor body, and which is abutted against one end of the operation arm and pivotally supported in the middle thereof. The display lever is moved by the other end of the display lever, and the display lever sets the distance from the pivot point to the contact position to the operation arm shorter than the distance from the pivot point to the contact position to the display arm. At the same time, during normal combustion, the display lever is arranged so as to be in contact with the operation arm so as to be inclined, and the contact portion has a substantially horizontal surface with respect to the operation arm.

Action The present invention has the above-described configuration, and the amount of movement of the display body relative to the amount of movement of the core up / down lever is sufficiently large to make it easier to see. The body will display the amount of combustion accurately.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.
In the figure, reference numeral 1 is a lead up / down lever for moving a wick 2 up and down, and the amount of combustion can be adjusted by moving the lead up / down lever 1 up and down. Reference numeral 3 is an anti-earthquake fire extinguishing device that lowers the wick 2 in the event of an abnormality such as an earthquake to extinguish the fire, and includes a weight 4, a lock plate 5, and the like. Reference numeral 6 denotes an operation arm attached to the core up / down lever 1, and as shown in FIG. 1, it opens / closes a micro switch 7 for controlling energization of, for example, an electronic odor absorber (not shown). Reference numeral 8 is an indicator driven by the operation arm 6 for displaying a combustion amount, and its configuration will be described below with reference to FIGS. 1 to 4. 9 is an operation plate attached to the front plate 11 of the combustor body 10,
Reference numeral 12 denotes a display lever pivotally supported on the back surface of the operation plate 9, and one end thereof is arranged so as to face the lower end of the operation arm 6 attached to the core up-down lever 1. The display lever 12 is arranged in an inclined state with respect to the core up / down lever 1, and the contact portion 12a with the operation arm 6 mounted integrally with the core up / down lever 1 is integrated with the core up / down lever 1. It is a horizontal plane so as to be orthogonal to the attached operation arm 6. Reference numeral 13 is a display member engaged with the other end of the display lever 12 and is provided between the guide pieces 14 of the operation plate 9 so as to be vertically movable.
It is biased downward by the spring 15. Here, the distance l from the pivot point 16 of the display lever 12 to the contact position to the operation arm 6 integrally attached to the core up / down lever is the distance from the pivot point 16 to the contact position to the display body 13. It is set smaller than L. In the figure, 17 is a plate for preventing the display body 13 from coming off,
18 is an ignition lever, 19 is an ignition knob, and 20 is a core upper and lower knob.

In the above structure, when the core up / down lever 1 is pushed down to raise the wick 2 from the state shown in FIG. 2, the operation arm 6 abuts on the abutment portion 12a of the display lever 12 and rotates the abutment portion 12a as shown in FIG. Then, the display 13 rises to display that the combustion amount is maximum. Then, when the core up / down lever 1 is lifted from this state to adjust the combustion amount, the display lever 12 rotates in the opposite direction as shown in FIG. 3, the display body 13 descends, and the fuel amount at that time is changed. indicate.

Here, in this indicator device, the pivot point of the display lever 12
The distance L from 16 to the display 13 is the distance l from the pivot point 16 to the operation arm 6 mounted integrally with the core up / down lever 1.
Since it is set to be sufficiently larger than the above, even a slight vertical movement of the core up-down lever 1 causes the display body 13 to move up and down greatly. That is, the enlarged display makes it easier to see.

Further, the contact portion 12a of the display lever 12 that contacts the operation arm 6
Since it is a horizontal plane, even if the operation arm 6 is shaken in the left-right direction as shown by arrow A in FIG.
The inclination angle of, that is, the position of the display body 13 is always held at the designed position, and accurate display is possible. That is, the fifth
As shown in the figure, if the contact portion 12a 'of the display lever 12' to the operation arm 6'is still tilted, the core up-down lever 1 '.
When is swung to the left or right as indicated by arrow A, the tilt angle of the operation arm 6'changes and the position of the display unit moves up and down as shown by the phase image line, so that accurate display cannot be performed. Disappears.

In the above embodiment, the operation arm 6 is provided on the core up / down lever 1 and the display lever 12 is operated by this operation arm 6, but this may be operated directly by the core up / down lever 1. Any configuration may be used as long as a part of the above is used.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the amount of movement of the display body can be set large, so that the combustion amount can be displayed in an easy-to-see manner, and the operation arm mounted integrally with the core up-down lever and Since the contact portion of the display lever which is in contact is flat, the influence can be absorbed even if the upper and lower sides of the core are slightly displaced to the left and right, and accurate display can be performed. Also, since the display lever is provided along the inner surface of the front plate of the combustor body, almost no space in the front-back direction of the combustor body is required, and the display function remains compact without increasing the size of the combustor body. Can be added.
